Prayer is meant to help you. If you feel the need to pray for money then do so. However, do not fall for the prosperity gospel being preached by TV. They want you to believe that if God loves you then you are going to be rich. God loves you, but you may never have all the money you want.
If you have a need, God will provide in one way or another. Keep your eyes and ears open, the prayer may be answered in a new job, new support, or something else entirely. Keep praying, God is listening.
